Chicken breast can be bought everywhere and is most nutritious, and this dish is easily prepared with ingredients found in the home kitchen. The yellow American mustard gives the color and flavor to this dish. The addition of the garlic just heightens the flavors. If you want to give it an “Asian” flavor, sprinkle with chopped coriander before serving. This is an ideal main dish for a dinner party at home.
In a large skillet or even the wok, over medium heat, melt butter with olive oil until it begins to sizzle; add chicken breasts. Cook over medium high heat, turning once, for about 15 minutes or until chicken is browned and fork tender.
Remove chicken from skillet; set aside. In the same wok add sour cream, milk, garlic and American mustard. Continue cooking, stirring constantly, until sauce is smooth and heated through. Pour sauce over chicken, garnish with green onions, sprinkle ground black pepper liberally over them and add coriander if desired.
